AI Technical Summary

Technical Problem

Existing embedded device firmware is easily copied by attackers in mass production scenarios, leading to intellectual property leakage and brand damage. Existing anti-copying solutions are costly or unsuitable for large-scale mass production.

Method used

By reading the multi-dimensional hardware characteristics of the target chip, a hardware fingerprint is generated, and combined with the locking information of non-volatile memory, autonomous binding and real-time verification are achieved to prevent firmware copying.

Benefits of technology

It increases the difficulty of preventing copying, reduces production configuration costs, and enables efficient offline mass production and real-time copy prevention, making it suitable for large-scale mass production.

Abstract

This application discloses a self-binding anti-copying method, system, and storage medium. The method includes: reading hardware features from a target chip; generating a first hardware fingerprint based on at least two types of the hardware features using a preset hybrid algorithm; reading locking information from non-volatile memory; determining that the first run is occurring when the locking information is empty or invalid; generating integrity verification data based on the first hardware fingerprint and binding data; combining the first hardware fingerprint, the binding data, and the integrity verification data to construct locking information; and writing it into the non-volatile memory. By reading the chip's multi-dimensional hardware features to generate a unique fingerprint, and automatically completing the binding process on the first run, the fingerprint is dynamically verified upon subsequent startups. This method achieves high-strength anti-copying protection without requiring an external server or dedicated security hardware, while greatly simplifying the mass production process.
